Sizing

Designed to comfortably fit a broader range of patients, AirFit F20 features an entirely new cushion design. To make fitting your existing patients easier, we recommend using our sizing guide – included in each AirFit F20 box and specifically designed to help patients find the right fit.
You can also download a copy of sizing guide here.

The arrow of your sizing guide should align with the top of your patient’s nasal bridge. The segment of the guide corresponding with the crease below your patient’s lower lip will indicate their recommended fit. If a patient falls between sizes, we recommend selecting a larger option for greater comfort.

AirFit F20 has three cushion sizes - small, medium and large. The modular design of the AirFit F20 means each size cushion easily clicks into the same mask frame for easier setup.

Fitting

Unclip EasyClick Magnets.

With your patient holding the mask towards their face, slide the headgear over the back of their head.

Reclip EasyClick Magnets.

Use the upper and lower headgear straps to help fine-tune their fit. Do not overtighten as this may cause discomfort.
This is also a good opportunity for your patient to reseat their cushion for comfort. When fitting is concluded, the cushion membrane should be fitting comfortably over your patient’s nasal bridge.
If your patient experiences leaks, or for additional information on mask maintenance and care, you can also visit the Supporting your patients section for more videos.

Fitting your AirFit F20

Unclip the EasyClick Magnets.

With the mask held against your face, pull the headgear over your head. Ensure the top of the mask cushion is sitting comfortably at the top of your nasal bridge. The bottom of your headgear should settle comfortably at the top of your neck - with the top of the headgear sitting on your crown.

Bring each of the magnets up to meet their corresponding clips on the frame.

To ensure your fit will work with your therapy:
Switch on your device and position yourself as if you are to begin therapy (e.g. lying down in bed).
Adjust your upper straps.
Adjust your lower straps.
Practice reseating your cushion – pull your mask away from your face, allow your cushion to reinflate, and then resettle the inflated cushion so the cushion membrane is sitting at the top of your nasal bridge.

Managing leak with your AirFit F20

Leak often occurs when your mask’s seal is compromised by movement, incorrect fitting or improper sizing.

To find a source of leak, run your finger along the edge of your mask’s seal. Once located, adjust your headgear.

Resolve any leak in the upper part of your mask by adjusting your upper straps.

Resolve lower mask leak with your lower straps.

If leak persists, reseal by briefly pulling your mask away from your face, letting your cushion reinflate, and resettling your mask cushion so the cushion membrane is sitting at the top of your nasal bridge.

If leak continues, you may need a different size mask. Try our sizing guide or speak to your healthcare provider about getting a different size mask.
